terminal 100. The display 151 may display a user interface (UI)
and/or a graphic user interface (GUI) related to a telephone call
when the electronic device 100 is in the call mode. The display 151
may also display a captured and/or received image, a UI or a GUI
when the electronic device 100 is in the video telephony mode or
the photographing mode.
The display 151 may include at least one of a liquid crystal
display, a thin film transistor liquid crystal display, an organic
light-emitting diode display, a flexible display and/or a
three-dimensional display. The display 151 may be of a transparent
type or a light transmissive type. That is, the display 151 may
include a transparent display.
The transparent display may be a transparent liquid crystal
display. A rear structure of the display 151 may also be of a light
transmissive type. Accordingly, a user may see an object located
behind the body (of the mobile terminal 100) through the
transparent area of the body of the electronic device 100 that is
occupied by the display 151.
The electronic device 100 may also include at least two displays
151. For example, the electronic device 100 may include a plurality
of displays 151 that are arranged on a single face at a
predetermined distance or integrated displays. The plurality of
displays 151 may also be arranged on different sides.
When the display 151 and a sensor sensing touch (hereafter referred
to as a touch sensor) form a layered structure that is referred to
as a touch screen, the display 151 may be used as an input device
in addition to an output device. The touch sensor may be in the
form of a touch film, a touch sheet, and/or a touch pad, for
example.
The touch sensor may convert a variation in pressure applied to a
specific portion of the display 151 or a variation in capacitance
generated at a specific portion of the display 151 into an electric
input signal. The touch sensor may sense pressure of touch as well
as position and area of the touch.
When the user applies a touch input to the touch sensor, a signal
corresponding to the touch input may be transmitted to a touch
controller. The touch controller may then process the signal and
transmit data corresponding to the processed signal to the
controller 180. Accordingly, the controller 180 may detect a
touched portion of the display 151.
The proximity sensor 141 (of the sensing unit 140) may be located
in an internal region of the mobile terminal 100, surrounded by the
touch screen, and/or near the touch screen. The proximity sensor
141 may sense an object approaching a predetermined sensing face or
an object located near the proximity sensor 141 using an
electromagnetic force or infrared rays without having mechanical
contact. The proximity sensor 141 may have a lifetime longer than a
contact sensor and may thus have a wide application in the mobile
terminal 100.
The proximity sensor 141 may include a transmission type
photo-electric sensor, a direct reflection type photo-electric
sensor, a mirror reflection type photo-electric sensor, a
high-frequency oscillating proximity sensor, a capacitive proximity
sensor, a magnetic proximity sensor, and/or an infrared proximity
sensor. A capacitive touch screen may be constructed such that
proximity of a pointer is detected through a variation in an
electric field according to the proximity of the pointer. The touch
screen (touch sensor) may be classified as a proximity sensor
141.
For ease of explanation, an action of the pointer approaching the
touch screen without actually touching the touch screen may be
referred to as a proximity touch and an action of bringing the
pointer into contact with the touch screen may be referred to as a
contact touch. The proximity touch point of the pointer on the
touch screen may correspond to a point of the touch screen at which
the pointer is perpendicular to the touch screen.
The proximity sensor 141 may sense the proximity touch and a
proximity touch pattern (e.g., a proximity touch distance, a
proximity touch direction, a proximity touch velocity, a proximity
touch time, a proximity touch position, a proximity touch moving
state, etc.). Information corresponding to the sensed proximity
touch action and proximity touch pattern may then be displayed on
the touch screen.
The electronic device 100 may include a fingerprint sensor 142 for
sensing a fingerprint for user authentication. The fingerprint
sensor 142 generates fingerprint recognition information from a
signal of a fingerprint recognition electrode. The fingerprint
sensor 142 may or may not include the fingerprint recognition
electrode.
The fingerprint sensor 142 according to one embodiment may be
implemented as a slide type sensor. The slide type fingerprint
sensor 142 can sense the fingerprint of a sliding finger to read
fragmentary fingerprint images and combine the fragmentary
fingerprint images into one image through image registration to
generate a full fingerprint image.
The fingerprint sensor 142 may include an additional recognition
window. When a user puts a finger on the recognition window and
slides the finger at a predetermined velocity, the fingerprint of
the finger can be scanned and fragmentary fingerprint images can be
acquired. The slide type fingerprint sensor may be referred to as a
bar type or linear fingerprint sensor according to the shape of the
recognition window.
The recognition window of the fingerprint sensor 142 may be
provided to the backside of the electronic device 100.
The fingerprint sensor 142 may be integrated with a touch panel of
the touchscreen 151 such that a fingerprint sensing layer overlaps
with at least part of the touch panel.
Accordingly, the electronic device according to an embodiment of
the present invention may receive fingerprint input applied to the
recognition window for fingerprint sensing or sense fingerprint
input through touch input in a predetermined pattern, applied to
the touchscreen in a fingerprint input mode.
The fingerprint sensor 142 may be integrated with a fingerprint
input module 133a shown in FIG. 2b, which will be described later,
in a package.
The audio output module 152 may output audio data received from the
wireless communication unit 110 or stored in the memory 160 in a
call signal receiving mode, a telephone call mode or a recording
mode, a speech recognition mode and a broadcasting receiving mode.
The audio output module 152 may output audio signals related to
functions, such as a call signal incoming tone and a message
incoming tone, performed in the mobile terminal 100. The audio
output module 152 may include a receiver, a speaker, a buzzer,
and/or the like. The audio output module 152 may output sounds
through an earphone jack. The user may hear the sounds by
connecting an earphone to the earphone jack.
The alarm 153 may output a signal for indicating generation of an
event of the mobile terminal 100. For example, an alarm may be
generated when receiving a call signal, receiving a message,
inputting a key signal, and/or inputting a touch. The alarm 153 may
also output signals in forms different from video signals or audio
signals, for example, a signal for indicating generation of an
event through vibration. The video signals and/or the audio signals
may also be output through the display 151 or the audio output
module 152.
The haptic module 154 may generate various haptic effects that the
user can feel. One example of the haptic effects is vibration. An
intensity and/or pattern of vibration generated by the haptic
module 154 may also be controlled. For example, different
vibrations may be combined and output or may be sequentially
output.
The haptic module 154 may generate a variety of haptic effects
including an effect of stimulus according to an arrangement of pins
vertically moving against a contact skin surface, an effect of
stimulus according to a jet force or sucking force of air through a
jet hole or a sucking hole, an effect of stimulus of rubbing the
skin, an effect of stimulus according to contact of an electrode,
an effect of stimulus using an electrostatic force, and an effect
according to a reproduction of cold and warmth using an element
capable of absorbing or radiating heat in addition to
vibrations.
The haptic module 154 may not only transmit haptic effects through
direct contact but may also allow the user to feel haptic effects
through a kinesthetic sense of the user's fingers or arms. The
electronic device 100 may also include a plurality of haptic
modules 154.
The memory 160 may store a program for operations of the controller
180 and/or temporarily store input/output data such as a phonebook,
messages, still images, and/or moving images. The memory 160 may
also store data about vibrations and sounds in various patterns
that are output from when a touch input is applied to the touch
screen.
The memory 160 may include at least a flash memory, a hard disk
type memory, a multimedia card micro type memory, a card type
memory, such as SD or XD memory, a random access memory (RAM), a
static RAM (SRAM), a read-only memory (ROM), an electrically
erasable programmable ROM (EEPROM), a programmable ROM (PROM)
magnetic memory, a magnetic disk and/or an optical disk. The
electronic device 100 may also operate in relation to a web storage
that performs a storing function of the memory 160 on the
Internet.
The interface 170 may serve as a path to external devices connected
to the mobile terminal 100. The interface 170 may receive data from
the external devices or power and transmit the data or power to
internal components of the electronic device 100 or transmit data
of the electronic device 100 to the external devices. For example,
the interface 170 may include a wired/wireless headset port, an
external charger port, a wired/wireless data port, a memory card
port, a port for connecting a device having a user identification
module, an audio I/O port, a video I/O port, and/or an earphone
port.
The interface 170 may also interface with a user identification
module that is a chip that stores information for authenticating
authority to use the mobile terminal 100. For example, the user
identification module may be a user identify module (UIM), a
subscriber identify module (SIM) and/or a universal subscriber
identify module (USIM). An identification device (including the
user identification module) may also be manufactured in the form of
a smart card. Accordingly, the identification device may be
connected to the electronic device 100 through a port of the
interface 170.
The interface 170 may also be a path through which power from an
external cradle is provided to the electronic device 100 when the
electronic device 100 is connected to the external cradle or a path
through which various command signals input by the user through the
cradle are transmitted to the mobile terminal 100. The various
command signals or power input from the cradle may be used as
signals for confirming whether the electronic device 100 is
correctly set in the cradle.
The controller 180 may control overall operations of the mobile
terminal 100. For example, the controller 180 may perform control
and processing for voice communication, data communication and/or
video telephony. The controller 180 may also include a multimedia
module 181 for playing multimedia. The multimedia module 181 may be
included in the controller 180 or may be separated from the
controller 180.
The controller 180 may perform a pattern recognition process
capable of recognizing handwriting input or picture-drawing input
applied to the touch screen as characters or images. The power
supply 190 may receive external power and internal power and
provide power required for operations of the components of the
electronic device 100 under control of the controller 180.
According to hardware implementation, embodiments may be
implemented using at least one of application specific integrated
circuits (ASICs), digital signal processors (DSPs), digital signal
processing devices (DSPDs), programmable logic devices (PLDs),
field programmable gate arrays (FPGAs), processors, controllers,
micro-controllers, microprocessors, and/or electrical units for

FIG. 2 is a front perspective view of a mobile terminal related to
the present invention.
The electronic device 100 includes a bar type body. However, the
present invention is not limited thereto and is applicable to
various types such as slide type, folder type, swing type, swivel
type, etc.
The body includes a case (casing, housing, cover, etc.) that forms
the exterior of the mobile terminal. In the present embodiment, the
case may be divided into a front case 101, a rear case 102 and a
battery cover 103. Electronic components are arranged in a space
between the front case 101 and the rear case 102. At least one
middle case may be additionally arranged between the front case 101
and the rear case 102.
The cases may be formed through plastic injection or may be made of
a metal, for example, stainless steel (STS) or titanium (Ti).
The display 151, the audio output module 152, the proximity sensor
141, the camera 121, the user input unit 130, etc. may be arranged
in the terminal body, mostly in the front case 101.
The display 151 occupies the main part of the front case 101. The
audio output module 152, the camera 121 and the proximity sensor
141 are located in a region adjacent to one edge of the display 151
and a front input unit 131 and the microphone 122 are arranged in a
region adjacent to the other edge of the display 151.
The front input unit 131 is an example of the user input unit 130
(refer to FIG. 1) and may include a plurality of manipulation units
131 and 132. The manipulation units 131 and 132 may be referred to
as a manipulating portion and may be implemented in a tactile
manner. The front input unit 131 is configured in the form of a
touch key in the present embodiment. However, the present invention
is not limited thereto and a push key may be added to the front
input unit 131.
Various inputs to the manipulation units 131 and 132 may be set.
For example, commands such as "start", "end", "scroll", etc. may be
input through the first manipulation unit 131 and a command for
controlling the volume of sound output from the audio output module
152 or a command for converting the mode of the display 151 into a
touch recognition mode may be input through the second manipulation
unit 32.
The manipulation unit 131 may be provided in the form of a button
and may be used as an interface for receiving a fingerprint of the
user. For example, the manipulation unit 131 may acquire
fingerprint information of the user in a capacitive manner.
Alternatively, the manipulation unit 131 may acquire the
fingerprint information of the user in a light detection manner
through a fingerprint input window provided to a predetermined
area.
In addition, the display 151 may form a touchscreen with a touch
sensor. In this case, the touchscreen can correspond to the user
input unit 130. This configuration enables the front input unit 131
to be omitted from the mobile terminal. Here, the mobile terminal
100 may be configured such that input manipulation for the terminal
body can be applied only through the display 151 and a rear input
module 133 which will be descried later.
Referring to FIG. 3a, a camera module 121' may be additionally
provided to the backside of the terminal body, that is, the rear
case 102. The camera module 121' may be a camera having a
photographing direction opposite to that of the camera 121 (refer
to FIG. 2) and including pixels different from those of the camera
121.
For example, the front camera module 121 preferably has low pixels
for taking a picture of a user face and transmitting the picture in
case of video telephony, whereas the rear camera module 121'
preferably has high pixels since the rear camera module 121'
captures an image of an object and does not immediately transmit
the captured image in many cases. The camera modules 121 and 121'
may be installed in the terminal body in such a manner that the
camera modules 121 and 121' can be rotated or popped up.
A flash bulb 123 and a mirror (not shown) may be additionally
provided in proximity to the camera module 121'. The flash bulb 123
flashes light at an object when the camera module 121' captures an
image of the object. The mirror is used for the user to see the
face when the user attempts to photograph (self-photograph)
themselves using the camera module 121'.
An audio output module 152' may be additionally provided to the
backside of the terminal body. The rear audio output module 152'
may implement a stereo function with the front audio output module
152 (Refer to FIG. 2) and may be used to implement a speaker phone
mode when the user makes a call using the mobile terminal 100.
A battery 191 for supplying power to the mobile terminal 100 is set
in the terminal body. The battery 191 is configured as an example
of the power supply 190. The battery 191 may be built in the
terminal body or detachably attached to the terminal body.
Referring to FIG. 3a, the rear input module 133 is provided to the
backside of the terminal body. The rear input module 133 is
configured as an example of the user input unit 130 (refer to FIG.
1). The rear input module 133 may be located adjacent to the camera
module 121' exposed from the backside of the terminal body.
The rear input module 122 is manipulated to receive commands for
controlling operations of the mobile terminal 100. Various inputs
may be applied to the rear input module 133. For example, commands
such as "power on/off", "start", "end", "scroll", etc., a command
for controlling the volume of sound output from the audio output
modules 152 and 152' and a command for switching the mode of the
display 151 to a touch recognition mode can be input to the rear
input module 133.
The functional modules provided to the backside of the terminal
body according to an embodiment of the present invention may be
modified or combined in various manners. For example, the
fingerprint input window 133 and the rear input module (not shown)
can be integrated into one module and implemented as a
multi-function input window capable of switching between a
fingerprint recognition mode and a user input reception mode can be
implemented.
Since the rear input module (not shown) is provided to the backside
of the terminal body, a new user interface using the rear input
module may be implemented. In addition, the fingerprint input
window 133 and/or the rear input module (not shown) provided to the
backside of the terminal body may replace at least some functions
of the front input unit 131 such that the display 151 can be
configured having a large screen when the front input unit 131 is
not provided to the front side of the terminal body.
While the backside of the terminal body can be provided as a hard
key type panel, such as the rear input module 133 shown in FIG. 3b,
the backside of the terminal body may be provided as a touch panel
133a having a predetermined size.
Accordingly, display of display 151 can be controlled through touch
input of the user, applied to the touch panel 133a provided to the
backside of the terminal body. In addition, it is possible to
control display of the display 151 by recognizing only touch input
in a predetermined pattern through the touch panel 133a provided to
the backside of the terminal body due to size restriction of the
touch panel 133a. For example, the touch input in the predetermined
pattern can include single touch input, multi-touch input or drag
input.
Furthermore, the touch panel 133a may execute the function of the
fingerprint input window for recognizing the fingerprint of the
user. In this case, the touch panel 133a may be packaged with the
fingerprint sensor.
The touch panel 133a may be arranged at a position where the touch
panel 133a can scan the fingerprint of the forefinger of the user
while the user grips the electronic device 100. However, the
present invention is not limited thereto and the position of the
touch panel 133a can be changed.
The fingerprint of the user may be recognized through input applied
to the rear input module 133 shown in FIG. 3a.
The functional modules provided to the backside of the terminal
body according to an embodiment of the present invention may be
modified or combined in various manners. For example, the rear
input module (133 of FIG. 3a) and the touch panel (133a of FIG. 3b)
can be integrated into one module.
When only one of the rear input module (133 of FIG. 3a) and the
touch panel (133a of FIG. b) is used, such module may be
implemented as a multi-function input means capable of switching
between a fingerprint recognition mode and a user input reception
mode.
Since the rear input module (133 of FIG. 3a) and the touch panel
133b) are provided to the backside of the terminal body, a new user
interface using the rear input module and the touch panel may be
implemented. In addition, the rear input module (133 of FIG. 3a)
and/or the touch panel 133a provided to the backside of the
terminal body may replace at least some functions of the front
input unit 131 such that the display 151 can be configured having a
large screen when the front input unit 131 is not provided to the
front side of the terminal body.
A description will be given of embodiments of the present
invention. It is assumed that the display 151 is a touchscreen 151
for convenience of description. As described above, the touchscreen
151 can execute both the information display function and
information input function. However, the present invention is not
limited thereto. In addition, touch described in the specification
may include both contact touch and proximity touch.
In the following description, user input for fingerprint
recognition, which is applied to the backside of the terminal body,
can be processed through at least one of the rear input module 133
of FIG. 3a and the touch panel 133a of FIG. 3b.
FIG. 4 is a flowchart illustrating a method of controlling an
electronic device for explaining the concept of the present
invention and FIGS. 5a to 5d show exemplary screens of the
electronic devices for explaining the method shown in FIG. 4 in
more detail.
The method of controlling an electronic device according to an
embodiment of the present invention may be implemented in the
electronic device 100 described with reference to FIGS. 1, 2 and 3.
A description will be given of the method of controlling the
electronic device according to an embodiment of the present
invention and operations of the electronic device 100 with
reference to the attached drawings.
Referring to FIG. 4, the controller 180 receives rear input through
the rear input unit (133a of FIG. 3b) (S100).
The rear input may be received while a predetermined image is
displayed on the touchscreen 151. The predetermined image may be an
application execution screen.
Referring to FIG. 5a, rear input can be applied by a first finger
F1 of the user to the rear input unit (133a of FIG. 3b) while the
application execution screen (page 1) is displayed on the
touchscreen 151.
Upon reception of the rear input, the controller 180 can control
the screen displayed on the touchscreen 151 to be temporarily held
(S110).
Here, temporary holding of the screen displayed on the touchscreen
151 may be recognized as holding the screen displayed on the
touchscreen 151 at the back of the mobile terminal as the rear
input is received. Furthermore, temporary holding of the screen may
refer to temporary storing of the screen such that the held screen
can be displayed again on the touchscreen 151 after additional
input is applied to the touchscreen 151.
The controller 180 may display a thumbnail of the temporarily held
screen on the touchscreen 151.
Referring to FIG. 5b, the page Page1 displayed on the front side of
the touchscreen 151 may be temporarily stored according to the rear
input F1 and a thumbnail P1 of the page may be displayed on the
touchscreen 151.
The controller 180 may provide a predetermined animation effect to
the page Page1 displayed on the touchscreen 151 according to the
rear input F1. For example, effect of temporarily reducing the size
of the page Page1 and dragging the same to the backside of the
terminal can be applied.
Simultaneously, the controller 180 may display a thumbnail tray 10
including the thumbnail P1 of the page Page1.
The thumbnail tray 10 may be displayed on a predetermined region of
the touchscreen 151, such as the top or bottom of the right side of
the touchscreen 151.
In addition, the thumbnail tray 10 may include thumbnails with
respect to a plurality of pages held according to the rear input
F1. Addition of thumbnails will be described later.
The controller 180 may receive predetermined touch input applied to
the touchscreen 151 while the rear input F1 is maintained and
execute a function corresponding to the predetermined touch
input.
Referring to FIG. 5c, the holding state of the first page Page1 is
maintained when the rear input F1 is maintained. However, the
controller 180 can execute a function corresponding to touch input
applied to the touchscreen 151 even if the first page holding state
is maintained. Accordingly, when touch input of flicking the
touchscreen 151 upward is received, a second page Page2 may be
displayed on the touchscreen 151.
When the rear input is released, the controller 180 may re-display
the temporarily held page on the touchscreen 151 and delete the
thumbnail indicating the temporary holding state (S130).
Referring to FIG. 5d, when the rear input F1 is released in FIG.
5c, the page Page1 temporarily held according to the rear input F1
can be displayed on the touchscreen 151.
An image in which the user is interested from among images provided
through the front touchscreen 151 of the electronic device 100 can
be temporarily held according to rear input, other images can be
searched through the touchscreen 151, and the held image can be
re-displayed on the touchscreen by releasing the rear input.
Therefore, it is possible to achieve the function corresponding to
the conventional bookmark function through simple rear input.
A description will be given of various embodiments that can be
implemented through the electronic device 100 by using input units
including not only the touchscreen 151 corresponding to the front
side of the electronic device but also the rear input unit.
FIG. 6 is a flowchart illustrating a method of controlling an
electronic device according to a first embodiment of the present
invention.
The method of controlling an electronic device according to the
first embodiment of the present invention may be implemented in the
electronic device 100 described with reference to FIGS. 1, 2 and 3.
The method of controlling the electronic device according to the

touch panel, as described above.
The controller 180 may store the first page displayed on the
touchscreen 151 in a standby state in response to the first input
(S220).
Here, storing the first page in the standby state means holding the
first page according to the first input applied through the rear
input unit. When the first input is released, the held first page
may be re-displayed on the touchscreen 151 as if the first page is
returned to the touchscreen 151 according to resilience.
When the first page is stored in the standby state, attributes of
the first page are stored with the first page. When the first page
is re-displayed on the touchscreen 151 as the first input is
released, the first page may be displayed with the attributes
maintained.
The controller 180 may receive a second input applied to the
touchscreen 151 (S230). The second input is touch input for
manipulating the first page displayed on the touchscreen 151 and
may include single touch input, double touch input, long touch
input, flicking input, etc. The second input applied to the
touchscreen 151 is received while the first input applied to the
rear input unit is maintained.
Accordingly, the user can store a desired page in the standby state
through rear input at any time by maintaining the rear input with
one hand and controlling the touchscreen 151 with the other
hand.
The controller 180 may execute a function corresponding to the
second input while the first page is maintained in the standby
state (S240).
The function corresponding to the second input will be described in
detail below.
The controller 180 may re-display the first page in the standby
state on the touchscreen 151 upon release of the first input
applied to the rear input unit (S250).
FIGS. 7a to 7e illustrate the method of controlling an electronic

PL3.
According to the third embodiment of the present invention, it is
possible to achieve effect of generating a new layer on the
touchscreen 151 as if a specific point of the touchscreen 151 is
opened through rear input. The effect of generating and displaying
a layer through rear input according to the third embodiment of the
present invention may be modified and implemented in various
manners.
FIG. 25 illustrates a method of controlling an electronic device
according to a fourth embodiment of the present invention.
The electronic device 100 according to the fourth embodiment of the
present invention can execute a function of capturing an image
using dual cameras. The function of capturing an image may include
a function of capturing a still image, a function of capturing a
moving image, etc.
The controller 180 may drive the camera (rear camera 121' of FIG.
3b) to display a first preview image 80 on the touchscreen 151.
Upon reception of rear input VC through the rear input unit (133a
of FIG. 3b) during capture of an image using the rear camera (121'
of FIG. 3b), the controller 180 may control the front camera (121
of FIG. 2) to operate. The controller 180 may display a second
preview image 82 acquired through the front camera (121 of FIG. 2)
on the touchscreen 151 such that the second preview image 82 and at
least part of the first preview image 80 overlap.
When key input for image capture is received while the first and
second preview images 80 and 82 are displayed on the touchscreen
151 and the rear input VC is maintained, the controller 180 may
execute a dual image capture function. An image captured by the
dual image capture function may be an image composed of the image
captured by the rear camera (121' of FIG. 3b) and the image
captured by the front camera (121 of FIG. 2) which are displayed in
an overlapping manner.
Upon release of the rear input VC, the controller 180 may turn off
the front camera (121 of FIG. 2) and display only the image
according to the rear camera (121' of FIG. 3b) on the touchscreen
151.
When the fourth embodiment of the present invention is applied to a
process of capturing a moving image, the electronic device 100 may
control a video corresponding to only a desired period to be
photographed by dual cameras during a video photographing
process.
That is, when the rear input VC is maintained for a period from a
first point to a second point during video capture through the rear
camera, the controller 180 may control only the video corresponding
to the period from the first point to the second point to be
captured by the dual cameras.
The fourth embodiment of the present invention is applicable to a
process of capturing a still image through the rear camera.
While the aforementioned embodiments of the present invention have
been respectively performed, the embodiments may be combined with
at least part of other embodiments.
